“He shall not put oil upon it” — if he places even a minimal amount of oil on a kezayit of this minchah, it is invalid. “Putting” implies any placement at all.
In the sugya: The absolute prohibition “lo yasim” is read to exclude even the smallest quantity of oil. Unlike ordinary menachos that require oil, this chatas flour is invalidated by any oil whatsoever.
Type of Learning
Diyuk of “lo yasim” — the prohibition is absolute; any oil, however little, disqualifies the chatas flour.
What Is Learned
Unlike ordinary menachos that require oil, the chatas flour must be completely free of oil. The slightest drop of oil on even an olive-bulk of the flour renders the offering pasul. The Torah’s negative language admits no minimal exception.
